Systems, Methods and Devices for Trusted Transactions
Abstract
The invention discloses a system for enhancing trust in
transactions, most particularly in remote transactions between a
plurality of transactional parties, for instance a seller and
buyer(s) of goods and/or services over a public computer network
such as the internet. Trust is disclosed to be a multivalent
commodity, in that the trust that is to be enhanced relates to
information about the subject matter of the transactions (e.g., the
suitability of the goods and services sold), the bona fides of the
supplier of the goods and services, the appropriateness of a
pricing structure for a particular transaction or series of
transactions, a quantum of additional transactional value that may
be imparted to the transactional relationship, security of
information exchange, etc.

BACKGROUND OF THE INVENTION
[0004] 1. Field of the Invention
[0005] This invention relates to the transfer of information
between parties; in particular, it relates to systems, methods, and
devices for trusted transactions.
[0006] 2. Description of the Related Art
[0007] Transactions are increasingly characterized by the amount
and quality of information available to market participants.
Whereas a seller seeks profit driven arrangements, which may vary
over the course of a relationship with a particular buyer or
consumer; buyers seek satisfaction of at least one of the
following: price, selection or service. At any time the buyer or
seeker of value-added information may lack recognition of the
seller or provider of such information, even if coupled with a
"manufactured" product or good. Sellers, or providers, similarly
lack any information about individual buyers, buying groups or
agents, and may only have information regarding potentially
profitable transaction events defined by at least one of the
following: existing market for goods or services, targeted
projected market for new goods or services, or those consumers or
buyers who currently engage in transactions with the provider.
Transactions are the result of customer profiting, a form of
recognizable pattern analysis for commerce.
[0008] Transactions conducted electronically, often in an online
environment taking advantage of networks, such as the Internet
and/or World Wide Web ("WWW"), form an increasingly-important
subset of transactions. Most obviously, retail sales transactions
in which individual customers purchase goods or services from a
central web server using a WWW connection have become a prominent
form of electronic transactions, though such transactions are by no
means the only or even necessarily the predominant category of
electronic transactions.
[0009] Electronic transactions pose special challenges for
transaction parties. Some of these challenges relate to the
difficulty of providing to a prospective acquirer (e.g., a
purchaser) of goods or services full, accurate, and verifiable
information regarding the nature, value, authenticity, and other
suitability-related characteristics of the product in question.
This is true in part, for instance, because the customer cannot
necessarily handle, sample, or evaluate at first hand the goods or
services in question in an online transaction to the same extent to
which he could evaluate them in an in-person transaction. It may
also be true because of the fear of counterfeit, defective, or
otherwise unsuitable products that may be viewed as more easily
"passed off" (assuming a certain non-zero incidence of deceit
and/or inadequate suitability verification among suppliers of
products) in an electronic transaction than in an in-person
transaction.
[0010] Further challenges in online transactions revolve around the
serious concerns regarding security of such transactions. Such
security-related concerns arise from the inherently-vulnerable
nature of distributed public networks such as the internet, in
which transaction parties cannot necessarily determine the path by
which data travelling to and from them will take. Nor is it always
possible to determine the identity of another transaction party, or
to ensure that such other transaction party will take adequate
precautions with sensitive data (for instance, data related to the
identity or financial details (e.g., credit card number) of the
first transaction party) transmitted during the course of
proposing, evaluating, negotiating, executing, or fulfilling a
transaction. Thus, concerns are raised about interception,
inadequate safeguarding, or other unauthorized or inappropriate use
of data generated or transmitted between transaction parties. Such
concerns have raised the perceived need for security technologies
adaptable for online transactions. Generically, these technologies
have included encryption, scrambling, digital watermarking, and
like methods of protecting transaction-related data.
[0011] Two conventional techniques for providing confidentiality
and/or authentication currently in use involve reciprocal and
non-reciprocal encrypting. Both systems use non-secret algorithms
to provide encryption and decryption, and keys that are used by the
algorithm.
[0012] In reciprocal algorithm systems, such as DES, the same key
and algorithm is used to encrypt and decrypt a message. To assure
confidentiality and authenticity, the key is preferably known only
to the sending and receiving computers, and were traditionally
provided to the systems by "secure" communication, such as
courier.
[0013] In non-reciprocal systems, such as those described in U.S.
Pat. No. 4,218,582, a first party to a communication generates a
numerical sequence and uses that sequence to generate
non-reciprocal and different encrypting and decrypting keys. The
encrypting key is then transferred to a second party in a
non-secure communication. The second party uses the encrypting key
(called a public key because it is no longer secure) to encrypt a
message that can only be de-crypted by the decrypting key retained
by the first party. The key generation algorithm is arranged such
that the decrypting key cannot be derived from the public
encrypting key. Similar methods are known for using non-reciprocal
keys for authentication of a transmission. In the present
invention, the non-secure "public" key is used to a message that
has been encrypted using a secure "private" key known only to the
originating party. In this method the receiving party has assurance
that the origination of the message is the party who has supplied
the "public" decrypting key.
SUMMARY OF THE INVENTION
[0014] Thus, a need has arisen for a system and method for
enhancing trust on the part of participants in transaction. This
may be with respect to all aspects of the transaction as to which
trust may be an influential factor (or, viewed negatively, in which
the lack of trust may be a potential bottleneck prohibiting
consummation of the transaction, or of a more-optimal transaction,
or of a series of transactions in a mutually-beneficial
transactional relationship).
[0015] A need has also arisen for trust enhancement for
transactions in connection with sophisticated security, scrambling,
and encryption technology, for instance that provided by
steganographic encryption, authentication, and security means.
[0016] A need has also arisen to provide these technologies in an
integrated method and system, optimally requiring comparatively
little processing resources so as to maximize its usefulness and
minimize its cost.
[0017] The present invention represents a bridge between
mathematically determinable security and analog or human measures
of trust. These measures are typically perceptible or perceptual
when evaluating value-added information. Additionally, a higher
level of transparency between parties is assured, because
information flow is recognizable and controllable by transacting
parties at will.
[0018] According to one embodiment of the present invention, a
method for trusted transactions is provided. The method includes
the steps of (1) establishing an agreement to exchange
digitally-sampled information between a first and a second party;
(2) exchanging the digitally-sampled information between the first
and the second party; and (3) approving the digitally-sampled. The
digitally-sampled information may be approved with an approval
element, for example, a predetermined key, a predetermined message,
or a predetermined cipher. The step of approving the digital
information may include authorizing the digital information with
the approval element, verifying the digital information with the
approval element, or authenticating the digital information with
the approval element. The predetermined cipher may be a
steganographic cipher or a cryptographic cipher.
[0019] According to another embodiment of the present invention, a
method for conducting a trusted transaction between two parties
that have agreed to transact is provided. The method includes the
steps of (1) establishing a secure transmission channel between the
two parties; (2) verifying an identity of at least one of the
parties; (3) determining an amount of value-added information to be
exchanged between the parties; (4) verifying the agreement to
transact; and (5) transmitting the value-added information. The
value-added information may include value-adding components.
[0020] According to another embodiment of the present invention, a
method for conducting at least one trusted transaction between two
parties is provided. The method includes the steps of (1)
authenticating the parties; (2) agreeing to a security of a
transmission channel; (3) exchanging secondary value-added
information; (4) determining at least one term for a primary
value-added information exchange; and (5) facilitating payment for
the transaction based on the terms.
[0021] According to another embodiment of the present invention, a
method for conducting a trusted transaction between two parties is
provided. The method includes the steps of (1) establishing a
steganographic cipher; (2) exchanging secondary value-added
information between the parties; (3) agreeing to terms for the
exchange of primary value-added information; and (4) facilitating
payment for the transaction.
[0022] According to another embodiment of the present invention, a
method for conducting a trusted transaction between parties is
provided. The method includes the steps of (1) identifying a unique
identification for each of the parties, a unique identification of
the transaction, a unique identification of value-added information
to be transacted, or a unique identification of a value-adding
component; (2) applying a steganographic cipher; and (3) verifying
an agreement to transact between the parties. Once the parties are
identified by the unique identification, transaction
identification, or the unique identification of the value-added
information, secondary terms and conditions may be offered for
acceptance. The transaction may take several additional steps and
may include additional value-adding components to reach a legal
agreement.
[0023] The agreement may cause a secondary term to be enabled for
one of the parties. For example, the agreement may be related to
the ability to choose ownership in the seller instead of some
benefit in price, service or selection. This ownership may be
priced according to traditional options pricing methodologies.
Essentially the "discount" in cash value terms, may be the option
price. So if there is a price, selection or service that can be
equated to some cash equivalent amount, that amount can be used by
the buyer as a right, but not obligation to purchase equity in the
seller. Alternatively, the cash equivalent may have a direct
equivalence in equity prices.
[0024] According to another embodiment of the present invention, a
method for hi-directionally exchanging value-added information
between parties is provided. The method includes the steps of (1)
associating a plurality of unique identifiers with the value-added
information, the value-added information including a digital
watermark, a file header, a file attachment, and/or a file wrapper;
(2) associating each of the parties with unique identifiers, the
unique identifiers including a digital watermark, a file header, a
file attachment, and/or a file wrapper; and (3) exchanging
value-added information between the parties.
[0025] According to another embodiment of the present invention, a
method for exchanging value-added information between parties is
provided. The method includes the steps of (1) providing a data
transmission means; (2) verifying the parties to the transaction;
(3) negotiating a term. such as a price, a service, and/or a
selection; and (4) binding the term to the information using a
digital watermark, a file header, metadata, and/or a file wrapper.
The bound transaction terms may include value-added
information.
[0026] According to another embodiment of the present invention, a
method for trusted transactions is provided. The method includes
the steps of (1) receiving data to be processed; (2) determining a
structure of the data; (3) determining if the data is authentic;
and (4) determining an associated usage of the data based on the
data structure and the authenticity of the data.
[0027] According to another embodiment of the present invention, a
method for secure transaction is provided. The method includes the
steps of (1) receiving a request to process a transaction; (2)
uniquely identifying the source of the request; (3) uniquely
identifying at least one term of the request; and (4) storing
identification information for transaction negotiation.
[0028] According to another embodiment of the present invention, a
method for the facilitation of the exchange of information data
between at least a first party and a second party is provided. The
method includes the steps of (1) receiving a rule governing
information data from a first party; (2) receiving a request for
the information data from a second party; (3) matching the
predetermined rule with the request; and (4) uniquely identifying
the information data and the first and second parties. The
information data may include unstructured data or structured
data.
[0029] According to another embodiment of the present invention, a
method for the management of rights is provided. The method
includes the steps of (1) receiving information; (2) determining
whether the information is structured information or unstructured
information; (3) identifying the information with a steganographic
cipher; (4) authenticating the information with a digital signature
or a digital watermark check; and (5) associating the
identification and authentication results with a predetermined
record, a predetermined rule, or a predetermined function.
[0030] According to another embodiment of the present invention, a
method for risk management is provided. The method includes the
steps of (1) receiving information; (2) determining whether the
information is structured or unstructured; (3) identifying
information with a predetermined ciphered key; (4) authenticating
information with a digital signature, a digital watermark check, or
a predetermined ciphered key; (5) associating identification and
authentication results with a predetermined rule; and (6) limiting
access based on a predetermined exposure of a decision maker.
[0031] According to another embodiment of the present invention, a
method for securely exchanging information data between parties is
provided. The method includes the steps of (1) creating a private
key; (2) deriving a corresponding public key corresponding to the
information data sought and at least one of (a) verifiable data
associated with different versions of the information data, (b)
verifiable data associated with a transmitting device, and (c)
verifiable data associated with an identity of the party seeking
the information data; (3) establishing a set of one time signatures
relating to the information data; (4) establishing a hierarchy of
access to the set of one time signatures; (5) creating a public key
signature, the public key signature being verifiable with the
public key, including the hierarchy of access to the set of one
time signatures; (6) providing the information to a certification
authority for verification; and (7) verifying the one time
signature and the hierarchy of access to enable transfer of
predetermined data.
[0032] According to another embodiment of the present invention, a
method for authenticating an exchange of a plurality of sets of
information data between parties is provided. The method includes
the steps of (1) creating a plurality of hierarchical classes based
on a perceptual quality of the information data; (2) assigning each
set of information data to a corresponding hierarchical class; (3)
defining access to each hierarchical classes and to each set of
information data based on at least one recognizable feature of the
information data to be exchanged; (4) predetermining access to the
sets of information data by perceptually-based quality
determinations; (5) establishing at least one connection between
the exchanging parties; (6) perceptually recognizing at least one
of the sets of information data dependent on user provided
value-added information data; and (7) enabling a trusted
transaction based on verification, and associated access, governing
at least one of a set of information data sets.
[0033] According to another embodiment of the present invention, a
method for authenticating the exchange of perceptual information
data between parties over a networked system is provided. The
method includes the steps of (1) creating a plurality of
hierarchical classes based on a perceptual quality of the

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0056] In order to assist in the understanding of the present
invention, the following definitions are provided and are intended
to supplement the ordinary and customary meaning of the terms:
[0057] Authentication: A receiver of a "message" (embedded or
otherwise within the value-added information) preferably is able to
ascertain the origin of the message (or by effects, the origin of
the carrier within which the message is stored). An intruder
preferably cannot successfully represent someone else. Additional
functionality, such as message authentication codes, may be
incorporated (a one-way hash function with a secret key) to ensure
limited verification or subsequent processing of value-added
data.
[0058] Authorization: A term which is used broadly to cover the
acts of conveying official sanction, permitting access or granting
legal power to an entity.
[0059] Encryption: Encryption is a method of securitizing data. For
example, encryption may be data scrambling using keys. For
value-added or information rich data with content characteristics,
encryption is typically slow or inefficient because content file
sizes tend to he generally large. Encrypted data is sometimes
referred to as "ciphertext."
[0060] High Quality: A transfer path into the LCS Domain that
allows digital content of any quality level to pass unaltered.
"High Quality" can also mean unfettered access to all VACs.
[0061] Local Content Server (LCS): A device or software application
that can securely store a collection of value-added digital
information, such as entertainment media. The LCS has a unique
ID.
[0062] LCS Domain: A secure medium or area where digital content
can be stored, with an accompanying rule system for transfer into
and out of itself.
[0063] Low Quality: A transfer path into the LCS Domain that
degrades the digital content to a sub-reference level. In an audio
implementation, this might be defined as below CD Quality. Low
Quality can also mean no VACs are allowed in to the system.
[0064] One way hash function: One-way hash functions are known in
the art. A hash function is a function which converts an input into
an output, which is usually a fixed-sized output. For example, a
simple hash function may be a function which accepts a digital
stream of bytes and returns a byte consisting of the XOR function
of all of the bytes in the digital stream of input data Roughly
speaking, the hash function may be used to generate a "fingerprint"
for the input data. The hash function need not be chosen based on
the characteristics of the input. Moreover, the output. produced by
the hash function (i.e., the "hash") need not be secret, because in
most instances it is not computationally feasible to reconstruct
the input which yielded the hash, This is especially true for a
"one-way" hash function--one that can be used to generate a hash
value for a given input string, but which hash cannot be used (at
least, not without great effort) to create an input string that
could generate the same hash value.
[0065] Read-Only Media: A mass storage device that can only be
written once (e.g., CD-ROM, CD-R, DVD, DVD-R, etc.) Note:
pre-recorded music, video, game software, or images, etc. are all
"read only" media.
[0066] Re-writable Media: An mass storage device that can be
rewritten (e.g., hard drive, CD-RW, Zip cartridge, M-O drive,
etc.).
[0067] Satellite Unit: portable medium or device that can accept
secure digital content from a LCS through a physical, local
connection and that can either play or make playable the digital
content. The satellite unit may have other functionality as it
relates to manipulating the content, such as recording. The
satellite unit has a Unique ID.
[0068] Scrambling: For digitally-sampled data, scrambling refers to
manipulations of the data. Value-added or information rich data may
be manipulated at the inherent granularity of the file format,
essentially through the use of a transfer function. The
manipulations are associated with a key, which may be made
cryptographically secure or broken into key pairs. The manipulation
may be associated with a predetermined key, which may be made
cryptographically secure or made into asymmetric key pairs.
Scrambling is efficient for larger media files and can be used to
provide content in less than commercially viable or referenced
quality levels. Scrambling is not as secure as encryption for these
applications, but provides more fitting manipulation of media rich
content in the context of secured distribution. Scrambled data is
also called "ciphertext" for the purposes of this invention.
[0069] Encryption generally acts on the data as a whole, whereas
scrambling is applied often to a particular subset of the data
concerned with the granularity of the data, for instance the file
formatting. The result is that a smaller amount of data is
"encoded" or "processed" versus strict encryption, where all of the
data is "encoded" or "processed." By way of example, a cable TV
signal can be scrambled by altering the signal which provides for
horizontal and vertical tracking, which would alter only a subset
of the data, but not all of the data-which is why the audio signal
is often untouched. Encryption, however, generally alters the data
such that no recognizable signal would be perceptually appreciated.
Further, the scrambled data can be compared with the unscrambled
data to yield the scrambling key. The difference with encryption is
that the ciphertext is not completely random, that is, the
scrambled data is still perceptible albeit in a lessened quality.
Unlike watermarking, which maps a change to the data set,
scrambling is a transfer function which does not alter or modify
the data set.
[0070] Secure Electronic Content Distributor (SECD): An entity that
can validate a transaction with a LCS, process a payment, and
deliver digital content securely to a LCS. This may be referred to
as a "certification authority." SECDs may have differing
arrangements with consumers and providers of value-added
information or other parties that may conduct transactions, such as
business to business relationships. The level of trust place into
an SECD can be dynamically adjusted as transactions warrant or
parties agree.
[0071] Standard Quality: A transfer path into the LCS Domain that
maintains the digital content at a predetermined reference level or
degrades the content if it is at a higher quality level. In an
audio implementation, this might be defined as Red Book CD Quality.
Standard Quality may also refer to a particular set of VACs that
are allowed into the system.
[0072] Unique Identification, or Unique ID: A Unique ID is created
for a particular transaction and is unique to that transaction
(roughly analogous to a human fingerprint). One way to generate a
Unique ID is with a one-way hash function. Another way is by
incorporating the hash result with a message into a signing
algorithm will create a signature scheme. For example, the hash
result may be concatenated to the digitized, value-added
information which is the subject of a transaction. Additional
uniqueness may be observed in a hardware device so as to
differentiate that device, which may be used in a plurality of
transactions, from other similar devices.
[0073] Value-Adding Component (VAC): An attachment to the content
that enhances the user's experience of the content. VACs may be
metadata, headers, usage rules, etc. For music, some examples are:
album art, lyrics, promotional material, specialized playback
instructions. For other embodiments, the value-adding component may
relate to the consumer's personal information, preferences, payment
options, membership, or expectations over a transaction.
[0074] The agglomeration of value-adding components is "value-added
information." In the aggregate, value creation on an informational
level can be observed and measured.
[0075] Value-added Information: Value-added information is
generally differentiated from non-commoditized information in terms
of its marketability or demand, Which can vary, obviously, from
each market that is created for the information. By way of example,
information in the abstract has no value until a market is created
for the information (i.e., the information becomes a commodity).
The same information can be packaged in many different forms, each
of which may have different values. Because information is easily
digitized, one way to package the "same" information differently is
by different levels of fidelity and discreteness. Value is
typically bounded by context and consideration.
[0076] Verification: Called "integrity," in cryptography, an
intruder preferably cannot substitute false messages for legitimate
ones; the receiver of the message (embedded or otherwise within the
value-added information) preferably is assured that the message (or
by effects, the origin of the carrier within which the message is
stored) that the message was not modified or altered in
transit.
[0077] Note: The above definitions may be interchanged in different
embodiments of the present invention and serve as parameters in
breaking down value-added information exchange and trusted
transactions.
[0078] Embodiments of the present invention and their technical
advantages may be better understood by referring to FIGS. 1 through
13, like numerals referring to like and corresponding parts of the
various drawings.
[0079] Increasingly, a premium is being placed on both recognition
and trust. These intangible elements are both expensive to create
and to maintain given the ever-decreasing amount of human contact
during transactions. To the extent that many transactions are now
possible without any human contact, the present invention is a
unique improvement over the art in enabling bi-directional
authentication of information between parties to enable "trusted
transactions" between those parties.
[0080] For anonymous market exchanges, transparency and data
integrity, as well as confidence, serve to promote confidence and
growth in product, goods and service offerings. Perception is an
expensive trigger to trusted transactions reinforced by the
experience of market participants.
[0081] Confidence as well as experience enable trust: in an
anonymous marketplace, it is desirable for the authenticity of
value-added information and value-added components to be made more
transparent and independently verifiable by all concerned parties.
Transparency is valued in education and experience.
[0082] A purchase decision between a buyer and a seller is
equivalent to the temporal establishment of a mutually agreed
"abstraction of value" in the information sought or exchanged,
which may be represented in both tangible and intangible forms.
Perception is the natural limit of "fair pricing," and drives value
determination of a particular good or service. Perception may be
structured by context, history, and/or condition. The "value" of a
particular transaction has an intrinsic meaning (financial,
economic, legal, political, social, statistical or actuarial
meaning), temporally (at the instant of the transaction), for both
the buyer and seller (reached an agreement including offer
acceptance and consideration), with any inclusive terms and
conditions (hereinafter, "terms") governing the transaction (price,
credit terms, delivery options, and other parameters concerning the
good or service with respect to which the transaction takes place).
As a result of such trusted transactions, the parties gain
confidence. Even parties who may be anonymous benefit from the
contemplated improvements over the art.
[0083] Referring to FIG. 1, a block diagram of a system for trusted
transactions is provided. System 100 includes trusted transaction
engine 102, which interacts with a plurality of parties 104. Each
party 104 has a unique identity 106.
[0084] Value-added information 108, as defined above, includes both
intrinsic value 112 and nonintrinsic value 114. A vendor (who may
be a party 104) may decide what information has value (i.e., should
be considered to have intrinsic value or not), and this decision
may be made on a per transaction basis.
[0085] The present invention may provide advantages to all parties
involved, including pricing flexibility, a reduction (or
optimization) of transaction costs, a recognition of value-adding
components, and the ability to provide provable security and trust
among parties. Each will be discussed in greater detail, below.
[0086] 1. Pricing Flexibility for Parties
[0087] Because buyers and sellers have complementary but
competitive goals in consummating a transaction, variable pricing
in the present invention is supported without any detrimental
affect on the potential relationship between the buyer and the
seller, or their agents. Known systems depend primarily on securing
payment; payment alone, however, does not ensure the buyer and the
seller of lasting protection of their respective "intangible
assets," especially those that are increasingly based on
value-adding information (e.g., trademarks, copyright, patents,
credit history, health condition, etc.). The buyer fears identity
theft ("first party," or "sentimental" piracy), While the seller
fears piracy of valuable information assets ("third party," or
"positional" piracy). The separation of authentication of
perceptually-represented goods and services and value-adding
information, from payment security, is an important novel feature
of the present invention.
[0088] Known systems specify a number of methods for ensuring
"security." However, the primary feature of these approaches is
access control based solely on proof that a purchase has been
completed. This means that if a purchase can be enabled only by
determinations that a transaction was successful, the ability to
entice more transactions or otherwise increase the development of
maintainable trusted transactions is undermined. Simply, the fact
that a purchase was completed does not mean that a trusted
transaction has, in fact, been enabled. No provision for
establishing a trusted relationship between the buyer and the
seller takes place absent some authenticable exchange of additional
value-adding information. The present invention increases the
likelihood of a successful trusted transaction and extends beyond
the ability to pay (assuming no "identity theft" has occurred). The
present invention provides additional means for verifiable
information exchange that enhance the experience of the buyer and
the seller in seeking trusted transactions.
[0089] Because many manufactured goods are likely to have similar
costs from a strict manufacturing standpoint, the value-added
service, or services, that are provided to the buyer are likely to
encourage additional opportunities for trusted transaction. The
seller can benefit by leveraging a single purchase into a
profitable relationship. Even distribution costs may be
commoditized for all similar tangible goods. A series of
non-contiguous or non-temporal transactions alone would constitute
a profitable relationship if the buyer is satisfied and the seller
is profiting. That pricing, and its terms, may be varied
dynamically or supported flexibly (based on information exchange at
the time or leading to a transaction), is another improvement over
the art. The incorporation of micropayments becomes more feasible
as the cost of trust has been reduced and thus smaller discrete
increments of monetary consideration are easier to support to the
benefit of buyers and sellers seeking higher granularity or
discreteness over the information or tangible goods they transact.
Simply put, identification and authentication of specific
information and value-added components is inherently important to
further segmentation of units of payment (e.g., micropayments).
Micropayments may be interpreted as a value-added component in
facilitating transactions.
[0090] Pricing may also be bi-directional and asymmetric, and is
preferably determined by the seller in order to define
"profitability." Some sellers may choose to maintain fixed pricing
for their goods or services, but may incorporate variable pricing
in the value-added component. For instance, while the price of a
given good or service may be fixed, the value-added component may
be the terms of the pricing as it effects the buyer. The seller may
also entice the buyer to provide demographic value-added
components, or related data, which has intrinsic, sentimental value
to the buyer. To the seller, the pattern, or structure, of
demographic datum serves as a valuable filter in which to position
its offerings. Simply put, while barter is relatively inefficient,
cash, being anonymous, may not reveal enough information to provide
an incentive for the seller to vary credit terms or offer a greater
variety of goods and services, even if there is a single underlying
value-added information good (the seller can still offer
perceptually similar but nonequivalent versions of the information
without threatening secure, higher quality, limited, or more
expensive versions).
[0091] The ability to offer both secure and unsecure, or legacy,
versions of the same information based on a mutual disclosure and
mutual understanding of both the buyer and the seller is
particularly novel in the art. Moreover, privacy can be enhanced
and new, unproven and yet unsecure information can be offered
without jeopardizing the security of any pre-existing primary
value-added information whether it be music, images, currency,
electronic documents, chip designs, source code, legacy versions,
prior art, etc.
[0092] The period of payment, like the discreteness of the actual
payment, interest rate relating to a payment period, grace periods,
early payment benefits, variable interest rate based on the
seller's ability to assess the credit risk/worthiness of the buyer
or its agent, etc. is an element or component (a value-added
component) that may be changed to affect a transaction. Making
these components more transparent to buyers improves the
opportunity for enhancing and maintaining trust. It also enables
buyers and sellers to make mutually beneficial decisions based on
transparent, verifiable information or value-added components.
Moreover, buyer-driven pricing, as with Dutch auctions, or
market-based pricing, are not possible without compromising the
access-based security in known systems. With the present invention,
goods and services are better able to realize fall market value
because access to the good or service is not restricted (such as
with new music or new endeavors by "unknown" or "unrecognized"
artists, designers, creators or engineers). The market participants
are better able to assess the good or service in question, and/or
the related value-adding information/component, when experience and
information sharing is encouraged. The prior art is restrictive by
necessity in information sharing precisely because security cannot
be maintained by prior art systems with such open access to
information.
[0093] For goods or services that are difficult to value (e.g.,
media content, legal advice, design, non-commodity items, etc.) and
decision-intensive, pricing becomes a barrier to entry in a
marketplace that puts a premium on recognition. Highly recognized
artists, lawyers, designers, retailers, etc. have a competitive
advantage over their unrecognized competitors. One approach to
gaining recognition is freely distributing or providing goods or
services. Ultimately, the seller still needs to profit from this
initial positioning to the extent that financing of operations is
available (the seller can stay in business as long as investors or
financing is available to enable such operations). The same goods
or services may be offered in a "tiered" manner, which relates to
the purchase price or to the quality of the underlying good or
service to be exchanged. Examples of this include providing music
in MP3 quality audio instead of CD quality; providing 10 hours of
customer support instead of charging per hour; charging service
charges instead of free checking or ATM access; charging a price
per bit or bandwidth; etc.
[0094] Segmenting also plays a role in the "freshness" or "newness"
of the information good or service. Live concerts or lectures may
be worth more to the buyer than pre-recorded versions offered later
or separately. The performer or creator of the information to be
performed, or conveyed live, can only be at one place at a time,
and may be a premium for that time. Live broadcasts may similarly
have a higher value. Physical advice may be worth more than printed
literature to the buyer as well. These dynamics create an impetus
for flexible and dynamic pricing that does not undercut the
security of the overall "trusted transaction" methods and systems
envisioned in the present invention.
[0095] In known systems, legacy information, relationships, etc.
systemically undermine the ability to ensure a "trusted system."
The buyer and the seller in the art have no means for
differentiating between the secure and unsecure versions of a good,
service, or value-adding component. The present invention provides
such protocols by incorporating additional bits of data, which do
not necessarily represent added data, but imperceptibly replace
data with identifying or authenticating data, enabling market
participants to determine whether a value-added information
"package" is secure. This also enables uniqueness of information
packages to be consistently created and checked or maintained for
later reference. The prior art relies on the denial of access or
access restriction, a clear disadvantage in increasing the
availability of value-added information. With trusted transactions
market participants are able to verify, identify, and price
information and then decide which versions are appropriate for a
given or existing demand.
[0096] Pricing may be better understood if the cost or time of
computation is measured as a tangible asset. Similarly, the natural
limit to theft of tangible assets has always been in the cost of
the tangible assets. As information can increasingly be traded for
value in excess of the cost of its storage or transmission, pricing
becomes less tangible and more subjective. Delivery of information
accurately and quickly becomes a valued service. Measuring such
value is based on the same principles that allow cost estimates of
the delivery of fixed weight parcel packages. The existence of
hackers indicates a lowered economic barrier to entry for
informational crime, including identity theft and piracy.
Dissemination of binary code, which is similarly detrimental, at
little or no cost to the originator of the valuable information,
introduces novel concepts to the approaches of information pricing.
Tangible goods become substitutes for cash payment.
[0097] An example of pricing based on effort is illustrated by a
watchmaker who takes six months to finish a watch that he prices at
$70,000. This includes a "reasonable" profit and the cost of
materials. The buyer is a watch fanatic and earns $140,000 a year.
The exchange of a tangible good that has intrinsic value, which is
converted into monetary terms for negotiation, as agreed by the
parties in the exchange, becomes more prominent if information
concerning value is transparent or fluid for all market
participants. Transparency is inherently favored by markets seeking
to appropriately price goods or services based on all available
information at the moment of pricing. Conversely, risk can be
priced based on the financial context or structure of an
organization. Those who earn $20,000 should have to have
confirmation by others with additional financial or fiduciary
responsibilities before validating or approving transactions that
exceed an individual's earnings for the period in question. At any
time responsibility can be linked to authority, as a pricing
mechanism for decisions concerning similar amounts of monetary
consideration. With pricing mechanisms and use rules, trusted
transactions offer flexible pricing not possible with current
systems.
[0098] Value-adding components, which may include pricing, is
preferably viewed as a separate and distinct means for the buyer
and the seller to separate information that may or may not be
essential to any given transaction and may also be viewed as
nonessential unless both parties can stipulate such information
exchange. This is invaluable as multiple channel distribution of
the "same" goods (e.g., download music over the Internet versus
purchasing a CD from a store) or services (obtaining a mortgage
online versus processing physical loan documents) can be offered by
the seller. Determinations of which channel, or channels, are
profitable requires verification of unsecure and secure versions of
these "same" goods.
[0099] Value-adding components may also include an offer, an
acceptance, a bid, a purchase, and a sale of a securities
instrument, including an option, a warrant, or equity.
[0100] Security is inherently intended for the party seeking value
or authentication over the information or transaction and
conversely protecting sentimental information or identity from
being stolen or defrauded. For the long term, buyers are able to
differentiate that personal information value-added components are
appropriate for dissemination to a seller to affect a transaction,
or to get better terms. Either the buyer or the seller, or both,
are better able to determine that transactions or relationships are
favorable on a transaction to transaction basis, and thus
"transact" accordingly.
[0101] Pricing of the value-added information may include a
value-adding component relating to the present value of
recognition/non-cash equivalent cost/service that is handled in a
separate negotiation or transaction, or a subsequent negotiation or
transaction.
[0102] The present invention may include limits of liability, or
may consider the time value of money when determining a limit of
liability threshold. The present invention may enable
rules/access/authorization based on the result of that operation.
In one embodiment, an actuarial estimate of liability (future time)
or cost (present time) may serve as a rule for enabling another
rule.
[0103] 2. Reduction or Optimization of Transaction Costs
[0104] In instances where the buyer and the seller, or their
agents, seek to transact products or services that include
value-added information, the seller generally seeks to maximize
profit, but may forego profit in the short term to ensure
recognition or market share in the short term. The buyer seeks
"satisfaction," which is dependent on one or more of the following
product/service determinants: 1) price; 2) service; and 3)
selection. These determinants may be quantitatively or
qualitatively assessed and may be based on available bandwidth,
time of transaction, and transaction event conditions.
[0105] A priori, the buyer may not recognize the seller. In an
information economy, such events are not a disincentive to pursuing
a trusted transaction, but instead present market opportunities for
valuing, authenticating, and verifying information (all may be
value-added components) concerning potential transactions are
inefficient. Conversely, the seller may not have enough information
about the buyer to determine what type of potential transaction can
be enabled, based on the buyer's ability to purchase now, or at any
point in the future. The seller may be inclined to make a sale with
the buyer (or the buyer's agents) with or without confidence that
the initial transaction will lead to further transactions or
trusted relationships that are profitable for the seller. The
seller may use purchasing options (e.g., barter, cash or its
equivalent, or credit) to enable a purchase by the buyer. According
to one embodiment of the present invention, because value-adding
information and its components may be bidirectional, both the buyer
and the seller may chose to negotiate the transaction, including
variable terms for payment, as one form of value-added component or
service and support for the information to be transacted.
[0106] Transactions, as defined by a purchase event (payment can be
preliminarily assured), may happen before or after the buyer and
the seller have "agreed" to transact. When the seller requires
value-adding components/information about the buyer before entering
the transaction, the seller generally has higher risks than the
buyer, which may affect its profitability. Where there is a high
risk for piracy, such as the digital copy problem (that can render
individual copies of value-added information worthless), the seller
may not be able to establish trust with an unknown buyer. The
seller is not assured of any potential profitable transactions or
long-term relationship with the buyer, which poses a significant
risk to the seller if the buyer pirates information goods or
services. A lack of dynamic authentication, even in real time, at
least initially, and adjusted as needs arise over time, and
flexibility in negotiable terms, may cause the seller's assets to
be economically undervalued.
[0107] Conversely, in those events where the buyer requires
value-adding components/information about the seller in advance of
entering a transaction, the buyer generally has higher risks than
the seller with regard to its ability to enter into transactions.
"Identity theft" is an example of a risk that is higher for the
buyer than the seller in these types of transactions. Additional
transactions include on-line brokering, auctions, searches, bots,
webcrawlers, recognition, and determination of goods or services
absent proof of privacy guarantees. This applies to noncommercial
information as well (e.g. the FDIC logo, currency, driver's
license, etc.) The establishment of mutual trust may be asymmetric
depending on the risk profile of the buyer and the seller.
Risk/reward tradeoffs are implicit to some transactions, while the
time required to establish a trusted transaction or eventual
profitable relationship may not be contiguous. In many on-line
transactions, the per transaction risk is generally higher to the
buyer, who may suffer fraud and may need to be more diligent about
what value-adding information it chooses to exchange in the
interests of enabling a trusted transaction. It is true, however,
that in business to business transactions ("B2B"), or in financial
information exchange, the relative risks to each party are
relatively equivalent, and requiring a more symmetric exchange of
value-adding components relating to verification and purchasing
power (in the form of barter, cash, cash equivalents or financing
that would also constitute value-adding components) is not as
necessary. Reducing the cost of creating and maintaining trust is
an advantage of the present invention over known systems.
[0108] 3. "Reintermediation": Recognition as a Value-Added
Component
[0109] Asymmetry exists in recognition as well. Where word-of-mouth
may constitute an acceptable means for creating recognition for a
particular good or service, the buyer and the seller may wish to
expand their respective abilities to capture more of the
increasingly available goods and services, or value-adding
information (about themselves, or terms for a trusted transaction).
With advertising and other forms of marketing, the push and pull of
value-adding information between the buyer and the seller also
contributes to potential purchase decisions by both parties or
their agents. The buyer may control certain criteria it seeks, such
as price, selection, and/or service. The seller, conversely, seeks
the highest profits from a given potential buyer or his agents,
which may not be quantifiable from the first transaction or may not
be the primary focus of the seller (such as seeking a valuable,
marquis client). Both the buyer and seller may compare patterns or
structure that, when recognized, help in forming opinions about the
history, condition or context of the information.
[0110] In general, recognition serves to encourage more
recognition. The seller will likely seek trusted transactions in
the interests of profitably leveraging the time, cost and expense
of generating the initial exchange of goods and services with the
buyer. Over the longer term (defined as any additional transactions
beyond the initial transaction), a profitable relationship is
sought by the seller. The buyer and the seller may still maintain
flexibility as expectations or needs concerning the relationship
change. The present invention allows for such variability and
flexibility by enabling real time adjustments to the terms that
prevail between market participants. While terms are conditions are
negotiatiable, security of the overall system is not jeopardized
because secure and unsecure versions of the "same" value-added
information and value-added components can be adjusted
bi-directionally. In an information-based transaction, there is
value in reintermediation by sellers seeking to ensure that their
information is provably identifiable and verifiable.
[0111] The buyer and the seller may seek recognition or use means
for increasing visibility of their respective interests. The buyer
ultimately seeks to satisfy itself through a trusted transaction
preserving private or financial information for select transactions
requiring higher amounts of information exchange or verification
(real time references, "membership reward programs" such as
frequent flier airline points, or financing options that can he
dynamically offered, are two incentives to the buyer and are likely
to differentiate vendors, large and small, really or perceptually);
the seller ultimately seeks to profit from the trusted transaction.
Recognition of this potential exchange between the parties is not
assumed to be high enough to enable a transaction, but high enough
to create exposure for the buyer or the seller. Trust is assumed to
not be pre-existing, or it may be variable between the buyer and/or
the seller, requiring additional exchanges of value-adding
information to enable a trusted transaction. The seller, in the
extreme, seeks the highest profit for each transaction. The buyer,
in the extreme, seeks the highest satisfaction for each
transaction. As discussed above, both goals are complementary and
competitive, thereby increasing the need for dynamic exchange of
value-adding information. Recognition can enhance the potential for
a successful trusted transactions and serves as a form of abstract
experience for both parties to efficiently make decisions. With
experience, value assessments become possible. Abstractions of
value become experience as trusted transactions beget more trusted
transactions.
[0112] 4. Provable Security and Trust
[0113] Trusted transactions are characterized primarily by bridging
the gap between "provable security" and the imprecise nature of
trust. Encryption, cryptographic containers, digital watermarks and
other forms of electronic data security can be mathematically
demonstrated--discrete algorithms can be designed to meet certain
pre-defined specifications or pre-defined expectations.
[0114] Encryption and secure digital watermarking (e.g.,
steganographic ciphering) offer tools for determining data
integrity, authenticity and confidence. Transactions, however,
still require human decision-making. Known systems describe a
number of approaches for ensuring transactional security based
solely on transmission security and fail to differentiate between
what could be called "positional piracy" (e.g., the fraud or theft
of universally recognized goods, products, and services) and
"sentimental piracy" (e.g., the fraud or theft of personal, private
or financial information).
[0115] For the purposes of this disclosure, the extreme case of
sentimental piracy is identity theft. So long as information can be
represented in binary digits (Os and is), and can be easily copied,
stored or transferred, identity fraud becomes an increasingly
insidious problem. There is a temporal limit whereby the actual
person is able to "reclaim" their identity at some point in time,
The extreme case of positional piracy is zero returns on an
intangible asset that has been pirated. As well, the present
invention offers advantages over known systems for positional
piracy that enable the continuation of legacy business, customer
relations and existing information formats, without sufficiently
weakening any overall system security for trusted transactions.
Simply, unlike known systems, access restriction is not an adequate
or appropriate means for ensuring the security of information data
for a wide variety of applications.
[0116] To the extent that "security by obscurity" is typically
representative of weak security to those skilled in the art of
cryptography, more transparency for parties to a transaction over
security protocols and information transfer are inherently
necessary to ensure trusted transactions. Although information
between parties may be asymmetrically exchanged (i.e., the
value-added information or value-adding components is not
equivalent in quality or quantity between parties, such as a
difference in the amount of information exchanged, the
identification of the parties, etc.), the level and degree of
authenticity or verification only differs among the goods, products
or services to be transacted, as well as the demands of the market
participants. For the purposes of this disclosure, the value-added
information is the fundamental good to be transacted between
parties, while value-added components represent an atomic unit of
data that is defined as the least amount of data that can either
add functionality or be perceptibly recognized to a system for
trusted transactions. Data may be represented in analog or binary
terms in order to establish uniqueness and assist in identification
and authentication. Value-added components may be added,
subtracted, or changed to vary the underlying value-added
information sought.
[0117] Because humans have difficulty remembering passwords,
personal identification numbers (PINs), and the like, dependence on
such datum is increasingly problematic as more anonymous
transactions are enabled between parties over electronic networks,
such as the Internet, or between businesses in private networks.
While passwords, or PINs, are commonly thought to be secure, the
ability to check all combinations of numbers or crack passwords
becomes less computationally expensive with increases in both
processing speed and availability of bandwidth. Cost is reduced to
the detriment of security if any individual has the means for high
order computation or network-based bandwidth in discovering or
hacking any given secret. Quantum computing speeds up the ability
to test and discover such data at even greater speeds, and presents
unique problems to security systems described in the art. Quantum
computing also enables the definition or predetermination of the
physical limitations of communicating or securing information.
Where difference between binary or digital signal processing and
quantum mechanical limits is higher, better security is
enabled.
[0118] Biometrics have been suggested to remedy this problem, but
do not offer any way to create truly cryptographic secrets to be
shared between parties. Iris scans, fingerprints, and the like, are
easily stolen because they are easily perceptible to those seeking
to defraud. Once stored electronically, biometrics be stolen for
unauthorized use. Combining a biometric with a digital signature
may provide a means to ensure that a given representation of a
fingerprint or iris is fixed, temporally at the time the
certificate is created, but does not prevent dedicated attacks at
determining the fingerprint or iris to be used at some subsequent
time. Real time authentication and verification are improvements
envisioned with the present invention. Assuring that a particular
fingerprint, signature or iris "data set" is that of the intended
user, is fundamentally important to embodiments described herein.
This becomes especially invaluable with increasing number of
anonymous transactions. Although uniqueness may be enhanced with
digital signatures and digital iris or fingerprint records, the
advantage with the present invention is that more secure forms of
uniqueness based on a predetermination of the discreteness of time
and a predetermination of the limits of information conversion and
transfer are absent in the art.
[0119] Moreover, real time authentication is not enhanced with
systems described in the art, since such biometric data is easily
stored or transferred, and thus suffers the same pitfalls for any
binary data that is sought by a party seeking to defraud.
Biometrics may be great for forensics (e.g., to determine after the
fact who is responsible for a particular act), but they do not
effectively address an inherent problem in enabling trusted
transactions; that is, real time verification of parties or real
time association of parties with information being transacted (in
an auction, for instance). They are also not representative of a
cryptographic key, which, as is well-known in the art, requires
secrecy, randomness, and an ability to update or destroy the
cryptographic key.
[0120] Another advantage of the present invention is the ability to
serialize or individualize "personal secrets" that are shared
between parties to boost confidence and transparency of
transactions. That control, and the inherent uniqueness of personal
entropy, constructed from such information as a hometown, favorite
restaurant, or high school sweetheart, is a means for perceptible
representations of "secret data" that enhances the ease-of-use and
application of appropriate shared secrets to be exchanged in
conducting trusted transactions. Associating such secrets with
primary value-added information or value-added components being
transacted is an additional novel feature of the present invention.
Essentially, the present invention provides the ability to
personalize or serialize, informationally, an actual "transaction
event," including: the buyer; the seller; primary information;
value-added components and tangible assets created, manufactured,
or manipulated; and any additional reference that can be made
perceptible and secure to any observer. Bridging cryptographic with
real world perception is a benefit over the prior art.
[0121] Essentially, randomness alone, whether pre-determined or
not, is not sufficient for the creation of a "secret" that may be
used with high levels of confidence repeatedly in assuring the
validity of information or verify the identity of a party.
Encryption systems cipher the randomness according to available
data capacity; digital watermarking ciphers the randomness
according to perceptible features or characteristics of the carrier
signal (a humanly-perceptible measure of data capacity, which
distinguishes applications for encryption from secure
watermarking). That such information can be made more
computationally difficult to discover, even by brute force attacks
(since such experience is only limited by the experience of
individuals) is of particular benefit to the art. The computational
complexity added by use of a steganographic cipher is discussed in
the U.S. Pat. No. 5,613,004, the disclosure of which is
incorporated by reference in its entirety, and offers a means for
human observers to see the actual tampering of information
represented perceptibly. This proof is self-similar to that which
is obvious in the real world, i.e., the ease at which one can
observe that a watermark is missing from currency. Handling
information as contemplated by the present invention for trusted
transactions is unique in bridging computational benefits from both
digital signal processing and cryptography to the benefits of all
parties to a transaction. The present invention is the enhancement
of transactions through bidirectional verification of parties and
verification of primary or secondary information exchanged.
[0122] An additional advantage of the present invention is the
ability to continue to offer legacy business relationships, legacy
products, legacy services and other means that will not reduce the
overall security maintained by a system for trusted transactions.
Known applications lack this feature, and instead rely on denial of
access or authorized access to information. Information need not be
restricted, and is preferably freely exchanged to widen the
opportunities for transactions with a greater potential number of
parties. The present invention is an improvement, in that the
elements necessary for generating trusted transactions may be made
more flexible, and those elements that are "secret," those elements
that will be available at predetermined times, as well as those
elements that are made more obscure to unintended parties, increase
the overall computational difficulties in defeating a system for
trusted transactions.
[0123] An additional consequence is improvements in enterprise
resource planning and data mining. To the extent that transactions
are made unique and may be atomized into data, functions,
value-added components and any associated information, the cost of
maintaining or referencing stored data, a goal in data mining
technologies, can be made more efficient and effective in assisting
with an optimized appropriation of resources, individual or
corporate. Without such uniqueness, serialization, authentication,
verification or identification, particular transaction events
cannot be analyzed, manipulated or optimally used to create
additional trusted transaction opportunities. Caching technologies
are similarly effected by the present invention. The choice about
what information should be maintained locally based on
identification or authentication of that information available on a
network, such as the World Wide Web, enables higher efficiency in
sorting and referencing data for repeated use without increased
demands on the network.
[0124] The ability to serialize individual transactions by
particularizing trusted transaction elements between parties is
handled more consistently than in known systems. Access is not
denied, and rules for access are not pre-determined for goods or
services that require exposure, testing or additional information
for consummating a transaction. Ease-of-use, maintenance of more
human-like and physical world expectations of trust are made more
transparent. Identity and authentication risk is reduced, and
confidence is increased. Overall expectations are handled according
to the needs of individual parties to any number of transactions.
What results from trusted transactions is a more vibrant and
competitive marketplace for information, value-added or not.
Anonymity and legacy relationships may be maintained, unlike
requirements in known systems.
[0125] The application of steganographic ciphers enables an
"optimized envelope" for securely inserting, detecting, and
protecting informational signals, or data, or digital watermarks
(predetermined messages) in a given digitized sample stream (e.g.,
a predetermined carrier signal, such as audio, video, image,
multimedia, virtual reality, etc.). As the perceptible qualities of
the content stream have a basis as analog waveforms, steganographic
ciphering increases the computational difficulty of crypto-analysis
and makes unauthorized removal or tampering of the watermark a
costly operation. With perceptible damage to a carrier signal a
result of such tampering, tampering is more easily observable by
parties, including those who are involved in a particular
transaction event. Moreover, such tampering enables higher
transparency and verification of carrier signals of datum that are
marked for secure exchange, even if over unsecure transmission
channels. The prior art relies overly on secure transmission
channels While ignoring the potential benefits of securing datum
(with secure watermarking, scrambling, or chaffing, for instance)
over any available transmission channel. Such tampering is also
transparent to vendors handling or accepting the information that
enables less costly validation of claims made after some event must
be confirmed and verified to the satisfaction of transacting
parties. These unique features are an improvement over the art.
[0126] What differentiates the "digital marketplace" from the
physical marketplace is the absence of any scheme that establishes
rights and responsibility, or trust, in the authenticity of
digitized goods, services or value-added information. For physical
products, corporations and governments watermark "goods" and
monitor manufacturing capacity and sales to estimate loss from
piracy. Reinforcement mechanisms, including legal, electronic, and
informational campaigns also exist to better educate consumers.
Evidentiary levels of confidence must exist to support claims that
are typically competitive between parties to a transaction.
[0127] Currently, security parameters may be coded into the actual
physical transaction system or instrument. Similar to the security
inherent in the randomness of the magnetic strip on most credit
cards, these security parameters are designed to be
tamper-resistant. Cracking such codes would not present
insurmountable barriers to a dedicated effort at cracking a PIN.
Access authorization is easily compromised by fraudulent
reconstruction of an instrument, such as a credit card. Although
storage of the security parameters in volatile, or nonpermanent,
memory appears to offer advantages, including higher security
required for many transactions, absent this higher level of
security, real time authentication becomes a crucial benefit to
parties in ensuring the validity of many forms of transactions.
Insurance, identity, and purchases of expensive items or services
are not generally confidently handled. Use of trusted transactions
to process value-added information is unique and beneficial.
[0128] Several components may be used for separation of "trusted
elements" for a given device or method for ensuring "trust"
according to one embodiment of the present invention. First, a
general purpose computing device is comprised of a CPU, a memory or
storage, input and output devices, and a. power supply. A device or
card holder decides whether and when to use the device. For
additional benefits described herein, personal information or
privacy data may be controlled by the user in sample embodiments
envisioned, unlike other pre-determinations of data in non-trusted
transaction smart cards (e.g., a credit card).
[0129] A data owner, who may or may not be the device holder, is
provided. Where the device holder and data owner are the same, as
contemplated by some embodiments of the present invention, such
data as digital certificates, time stamps, Unique IDs of data
coming into and out of the device (personal or financial
information being a large class of such data), etc. can be
authenticated in a humanly-perceptible manner. This may be
accomplished by a transducer, or a screen, that can transfer
analog-based information of device holder, or be inputted and
transmitted by the device holder for secure watermarking, or
hashing of data to be exchanged.
[0130] A terminal, controlling input and output to and from the
device (e.g., phone cards are controlled by the phone service
provider's terminals, ATMs are controlled by financial
institutions, set-top boxes controlled or owned by entertainment
distribution providers, etc. that may be made physically secure by
separate means) or a system that may interact with a device, such
as that contemplated in embodiments herein, to enable real time
authentication or verification where such checks may fail from
time-to-time with existing pre-defined trust arrangements or
pre-determined protocols that require inefficient updating by one
or both parties. In lieu of a physical visit to a vendor, the
present invention anticipates more convenient anonymous updates, in
those markets where it is possible to the benefit of both buyers
and seller--both parties have a market demand or need and are able
to agree to such arrangements.
[0131] Embodiments of the present invention may include a simple
Internet browser plug-in, with complementary system software for
the provider of "information goods or services," that would
identity, verify, authenticate, enable transfer, enable copying or
other manipulations of the various primary value-added information
and value-added components. Some of the functionality may strictly
indicate what, if any, security exists within a particular primary
value-added information set. This need not be settled within a
system of trust, but be inherently imperceptible to any casual
observer or market participant interested in the information or the
transaction events that can be observed. Essentially, encouragement
of provable differentiation between different classes of primary
value-added information (secure, unsecure, legacy, etc.),
value-added components (not the primary information but
value-adding to the transaction event, and any information
concerning market participants (private, history, condition, or
financial) is enabled, using simple steganographic ciphers with
mapping and transfer functions without compromising the underlying
security.
[0132] A device issuer controls the operation of the device
according to mutually agreed to terms between parties. The device
issuer may limit the use or functionality of the device.
[0133] For the device hardware manufacturer, fraud may be attempted
by the various parties, subcontractors, etc, who are involved in
the manufacture of the devices. The device issuer requires
protocols that cannot be defeated by typical "rogue engineer"
attacks, where security is dependent on an understanding of the
methodologies, device, or system design. In fact, the ability to
transparently and provably manufacture secure smart devices may be
accomplished with such protocols as digital time stamping (using
successive temporally related hashes that seed other hashes to
create a universally acceptable means for establishing the time of
manufacturer, with time being the universal constant), or digital
watermarking (where instead of time, other predetermined data is
concatenated with data for provably establishing ownership, over
the device). Tampering must be provably perceptibly evident upon
tamper detection of the device (as with device used for limiting
theft of clothing or physical items in retail stores). Prevention
of the rogue engineer problem is not anticipated by known
systems.
[0134] A software manufacturer usually requires clear
specifications or transparency such as open source code, providing
the underlying ciphering algorithms and other specifications for
analysis. Similar trust issues as with device hardware
manufacturing exist. Stega-ciphering the operating system, the
simple system or engine for determining authenticity and
identification of available data, to prevent memory capture,
cloning, write once memory specific to the device holder provide
additional benefits of security. A discussion of such is provided
in U.S. Pat, No. 5,745,569, the disclosure of which is incorporated
by reference in its entirety. As well, using transfer functions
with associated predetermined keys is also a means for
accomplishing confidence and authenticity in transaction. This is
described in U.S. patent application Ser. No. 09/046,627, entitled
"Method for Combining Transfer Functions with Predetermined Key
Creation," the disclosure of which is incorporated by reference in
its entirety.
[0135] In general, security requires: fewer splits of trust (poor
tying arrangements that may encourage fraud or piracy), better
transparency of data (it should be perceptibly apparent, or
mathematically, or actuarially possible to observe risks and
quantify them to enable security design with a clear understanding
of potential threats for each system, method or device), and use of
cryptographically strong protocols, where security is both provable
and perceptible such that market-driven features are both
fundamental at the earliest development and design of appropriate
systems and devices, in order to build confidence and trust that is
acceptable and transparent to all parties to a transaction.
[0136] Application of a steganographic cipher to the operating
system or operation of the contemplated systems and devices ensures
further security from tampering. Such methods are disclosed in U.S.
Pat. No. 5,745,569, and offer additional benefits when coupled with
the embodiments disclosed herein. System or device operations may
be controlled with minimum functionality, objects or executable
code. As value-added information is checked for authenticity,
decoding any embedded operation objects or code, executing the
operation of the system, and deleting the object or code from
memory, or randomizing it in memory to avoid capture, would greatly
increase the security of both value-added information and the
systems or devices intended for manipulation of the value-added
information, Alternatively, certain base functions, such as play,
record, copy, manipulate, and transfer data, may be problematic.
These functions may be atomized into objects that must be first
authenticated by the trusted transaction device before they are
operable for the given format, or before they provide additional
information.
[0137] Time of use has traditionally been a typical constraint for
securing smart cards and. similar devices, but may become
ineffective and inconvenient to users. Enabling a smart card to
capture or transduce information (even converting analog
information or input into secure digitally-sampled representations
of the analog information for analysis and authorization, as with a
stega-ciphered digital watermark) about the time, location,
identity or any number of specific datum greatly enhances smart
card and similar device security, trust and confidence. Such
benefits over known systems are valuable contemplated with the
present invention,
[0138] Valuations of trust also enables the described sample
embodiment of a trusted transaction system or device to compare
private information with financial information, essentially
bridging determinations of risk in financial transactions and
insurability, Private, or sentimental, information disclosure is
more highly sought in determining insurance risk, The ability to
pay, and other financial information, are being commoditized.
Insofar as the described method and device for such deployment of
trusted transaction technology can be assessed for different
products and markets, the example of an insurance device could
easily be called a trusted transaction privacy/financial
information device or card. Users can control what information they
disclose given the risk coverage or credit they seek, and providers
being able to decide, with more current and transparent information
disclosure possible, what to underwrite or what to finance.
[0139] For the authentication or identification device, there is a
risk of identity theft to both buyers and sellers, or information
that is limited by law. Examples include Medicare-covered drugs,
local legal constraints, etc. Risk may be predetermined or limited
by a government agency (FDIC, FBI, Social Security, IRS, DMV,
Federal Reserve, etc.), a similarly outfitted organization (trust
is held in perceived and observable representations of the
organization, food stamps, stamps), or an equivalent transaction
event enabler (traveler's check provider, medication, etc.). In
these cases, systemic risk is limited by enforcement agencies held
in trust by a government or body politic. The restrictions are
predetermined and dependent on successful authentication or
identification of a product, label, or other similar item. Laws may
differ between localities and may be dependent on some form of
identification, proof of age, or proof of residency. To properly
serve local residents becomes a data security issue. This
embodiment. offers advantages over the art in its flexibility and
real time, perceptible authentication properties.
[0140] Both the provider and the agency involved may have higher
levels of risk, because the nature of the information is
characterized by high value, general or universal recognizability,
and a genuine threat of fraud, Most people casually accept that $10
and $20 bills are real even if they prove not to be later.
Governments try to limit such liability without damaging the
overall trust in the currency. As abstractions of value are
exchanged, a smart identifying device, instead of value replacement
device (predetermined, fixed spending or authorization in a
device), is necessary to capture "personal entropy," or information
about oneself that can be more closely guarded and less open to
theft versus a password or pass phrase. Secrets must differ from
identification. The larger body of data to search to discover these
secrets act as a higher form of secrecy. These datum may be
converted to readable text in some embodiments or maintained in
digitally-sampled but humanly perceptible form in other embodiments
(favorite restaurant is represented as an actual image of the
restaurant, mother's maiden name is actually the voice of an
individual's maternal grandparents, highly specialized forms of
personal information that may be dynamically changed or checked
quickly and conveniently without undue risk exposure to the
system)
[0141] For governments and individuals, piracy of identity is the
most insidious risk exposure. Identity theft may be curtailed with
devices that can transduce, in real time, an iris scan, fingerprint
or other biometric and compare securely transmitted results with a
secured stored record at the time of initialization. Alternatively,
this may be accomplished with an unrelated Unique ID that confirms
the identity of the user, and may be created and stored on the
device. Because governments are arbiters of trust in markets (their
actions in the collective affect trust and confidence in products
and markets), these devices are able to alert consumers to
potential risk for a given product or service (represented by some
ruling or law that is important to convey to the consumer, such as
with alcohol, medications, or tobacco). These devices could, at the
discretion of the user, indicate related warnings for which the
government has an interest in safety. In one embodiment, by
checking an actual cigarette carton, or drug packaging, with the
enabled device, counterfeit packaging may also be detected. In one
embodiment of the present invention, bar code scanners may be
"required" to also check for embedded or associated signals
indicating authenticity. The devices may also check if supposedly
"real" prescription drugs are authentic. Such a check may occur
when using the device to communicate with a vendor and check to see
if any complaints or problems exist in stored records; again the
packaging may be checked for authenticity in cases where
counterfeits are high and difficult to check without some form of
secure watermarking or perception-based authentication that can be
efficiently handled by an enabled device.
[0142] According to one embodiment of the present invention,
digital content may be distributed through a local content sever,
or LCS. In general, the LCS environment is a logical area inside
Which a set of rules governing content use may be strictly
enforced. The exact rules may vary between implementations, but in
general, unrestricted access to the content inside the LCS
environment is disallowed. The LCS environment has a set of paths,
or paths that allow content to enter the domain under different
circumstances. The LCS environment also has paths that allow the
content to exit the domain.
[0143] The act of entering the LCS environment may include a
verification of the content (an authentication check). Depending
upon the source of the content, such verification may be easy or
hard. Invalidatable content may be subjected to a quality
degradation. This degradation may be to the content itself, or it
may be removal of value-added components. Content that can be
validated, but that belongs to a different LCS environment may be
excluded. The primary purpose of the validation is to prevent
unauthorized, high-quality, sharing of content between
environments.
[0144] When content leaves the LCS environment, it may be
watermarked as belonging to that environment. It is allowed to
leave the LCS environment at the quality level at which it was
stored (i.e., the quality level determined by the path). The
watermark on the exiting content may be both an embedded digital
watermark and an attached hash or digital signature (it may also
include a secure time stamp). Content cannot return into the
environment unless both the watermark and hash can be verified as
belonging to this environment. The presence of one or the other is
generally sufficient to allow re-entry.
[0145] This system may allow a certifiable level of security for
high-quality content, and may allow the use of unsecure content at
a degraded quality level. The security measures are such that a
removal of the watermark constitutes only a partial failure of the
system. The "wiped" content may be allowed back into the LCS
environment, but only at a degraded quality level, a result of the
watermark destruction and subsequent obscurity to the system.
Consumers will not be affected to the extent that the unauthorized
content has only been degraded, but access has not been denied to
the content. Only a complete forgery of a cryptographically-secure
watermark will constitute a complete failure of the system. For a
discussion on such implementations please see U.S. Pat. No.
5,613,004; U.S. Pat. No. 5,687,236; U.S. Pat. No. 5,745,569; U.S.
Pat. No. 5,822,432; U.S. Pat. No. 5,889,868; U.S. Pat. No.
5,905,800, U.S. Pat. No. 6,078,664, U.S. patent application Ser.
No. 09/046,627 U.S. patent application Ser. No. 09/053,628, and
U.S. patent application Ser. No. 09/594,719.
[0146] Provable security protocols may minimize this risk. Thus,
the embedding system that embeds the watermark does not need to be
optimized for robustness, only for imperceptibility (important to
publishers and consumers alike) and security (more important to
publishers and commercial interests in the content than to
consumers). Ideally, as previously disclosed, security preferably
does not obscure the content, nor prevent market participants from
accessing information contained therein, and for the longer term,
developing trust or creating relationships.
[0147] The system can flexibly support "robust" watermarks as a
method for screening content to speed processing, Final validation,
however, is relied upon the fragile, secure watermark and its hash
or digital signature (a secure time stamp may also be
incorporated).
[0148] The LCS provides storage for content, authentication of
content, enforcement of export rules, and watermarking and hashing
of exported content. Stored content may be on an accessible
rewritable medium, but is preferably stored as ciphertext
(encrypted or scrambled), not plain text, to prevent system-level
extraction of the content, This is in contrast to known systems,
Which affix or otherwise attach meta-data to the content for access
control by the variously proposed systems.
[0149] The LCS may be able to receive content from a secure
electronic content distributor, or SECD, and may be able to
authenticate content received via any of the plurality of
implemented paths. The LCS may monitor and enforce any rules that
accompany received content, such as number of available copies.
Finally, unless being transmitted to a satellite unit, the LCS may
watermark all exported material and supply a hash made from the
Unique ID and the content characteristics (so as to be maintained
perceptually within the information and increase the level of
security of the watermark).
[0150] The satellite unit enables the content to be usable apart
from the LCS. The satellite unit is partially within the LCS
environment. A protocol may exist for the satellite unit and LCS to
authenticate any path made between them. This path may have various
levels of confidence set by the level of security between the
satellite unit and LCS, and determinable by a certification
authority or its equivalent, such as an authorized site for the
content. The transfer of content from the satellite unit to the LCS
without watermarking may be allowed. However, all content leaving
the satellite unit is preferably watermarked. The satellite unit
watermark may contain a hash generated from the satellite unit
Unique ID and the content characteristics. If the content came from
a LCS, the satellite unit may also add the hash received from the
LCS to the watermark. The LCS and satellite unit watermarking
procedures do not need to be the same. However, the LCS is
preferably able to read the satellite unit watermarks for all
different types of satellite units with which it can connect. The
satellite unit does not need to be able to read any LCS watermarks.
Each LCS and satellite unit preferably has a separate Unique
ID.
[0151] Referring to FIG. 2, a schematic of a local content server
environment according to one embodiment of the present invention is
provided. LCS 202 may be a software device running on a general
purpose computing device, such as a personal computer (including,
in general, a central processing unit, an input, an output, a
memory, and a power supply). LCS 202 may include local content
server domain 204, rewritable media 206 (such as a hard disk drive,
a CD-R/W, etc), and read-only media 208 (such as a CD-ROM). LCS 202
may communicate with at least one satellite unit 210 via an
interface.
[0152] In one embodiment, LCS 202 may have a Unique ID. Similarly,
in one embodiment, satellite unit 210 may have a. Unique ID.
[0153] LCS 202 may communicate with SECD 212 via a network,
including a local area network, a wide area network, an intranet,
and the Internet. This communication may also be established by a
telephone link, a cable connection, a satellite connection, a
wireless connection, etc.
[0154] In one embodiment, a single LCS 202 may interface with more
than one SECD 212.
[0155] A plurality of paths 220, 222, 224, 226, 228, 230, 232, and
234 may exist among LCS 202, SECD 212, Satellite unit 210, LCS
domain 204, rewritable media 206, and read-only media 208. Each
will be discussed in greater detail, below,
[0156] Digital content may be securely distributed to LCS 202 from
SECD via path 220. The content may be secured during the
transmission using one or more security protocols (e.g., encryption
or scrambling of the content). In one embodiment, if LCS 202
interfaces with multiple SECDs 212, each path may use a different
security protocol.
[0157] The security protocol may use an asymmetric cryptographic
system. An example of such a system includes a public key
cryptography system. The private and public key pairs allow LCS 202
to authenticate and accept the received content.
[0158] Referring to HG. 3, a flowchart depicting an example of an
authentication by LCS 202 is provided. In step 302, the user
connects to the SECD, makes a selection, and completes a sale.
[0159] In step 304, the LCS provides its public key to the
SECD.
[0160] In step 306, the SECD uses the LCS public key to initiate
transmission security.
[0161] In step 308, the SECD transmits the secured digital content
to the LCS.
[0162] In step 310, the LCS receives the digital content,
authenticates that the digital content was unchanged during
transmission, and unpacks it from its security wrapper (that may
include a secured transmission line, such as SSL). In one
embodiment, the digital content may be authenticated by a watermark
and hash check. If the content can be authenticated, the content is
accepted into the LCS domain. If the content cannot be
authenticated, it is rejected.
[0163] Referring again to FIG. 2, path 222 connects LCS domain 204
with rewritable media 206. Referring to FIG. 4, a flowchart
depicting the process for content entering LCS domain 204 from
rewritable media 206 is provided. In step 402, the content is
provided. In step 404, the content is checked for the presence of a
watermark, such as a watermark for the particular LCS. If there is
not a watermark, in step 406, the content is degraded to Low
Quality and, in step 408, the content is stored in the LCS
domain.
[0164] If, in step 404, a watermark is present, in step 410, the
watermark is checked to determine if it matches the LCS. This may
he achieved by a hash. If the watermark is verified, in step 408,
the content is stored in the LCS. If the hash does not match, the
content is rejected.
[0165] Referring again to FIG. 2, LCS domain 204 may export content
to any receiver (other than satellite unit 210) through path 224.
This may include copying content to a rewritable media, creating a
read-only media, rendering the content for use (e.g., playing,
viewing, etc), etc.
[0166] Referring to FIG. 5, a flowchart depicting the process for
content leaving LCS domain 204 is provided. In step 502, the
content is retrieved from storage within the LCS. In step 504, the
content is embedded with a watermark. In one embodiment, the
watermark may be unique to the particular LCS, as determined by the
LCS Unique ID. The watermark may contain a hash that is created
from the combination of the content characteristics (such as signal
features, etc.) and the Unique ID. The watermark may optionally
contain other data, such as a timestamp, a number of allowable
copies, etc. This would be described as parameters of use, usage
data, etc. which could be referenced when content is exported. If
the export is to a storage medium, the LCS optionally can add a
second hash to the file, external to the content, which can be used
for further authentication. For security purposes, in one
embodiment, the external hash may be created in a different manner
from the embedded, watermark hash.
[0167] In step 506, the content is output from the LCS to the
receiver.
[0168] Referring again to FIG. 2, path 226 connects LCS domain 204
with read-only media 208. Referring to FIG. 6, a flowchart
depicting the process for content entering LCS domain 204 from
read-only media 208 is provided. In step 602, the content is
provided. In step 604, the content is checked for the presence of a
watermark, such as a watermark for the particular LCS. If there is
no watermark, a check is made in step 610 to see if the originality
of the content can be determined. An example of such includes a
media-based identifier that identities the content as original.
[0169] If the content can be verified as an original, in step 608,
it is stored as High Quality in the LCS domain. If the originality
cannot be verified, in step 610, the quality is degraded to
Stand-Quality, and, in step 608, the content is stored in the LCS
domain.
[0170] If a watermark is identified in step 604, in step 612, the
hash is checked to verify that the content matches this LCS. If it
matches, in step 608, the content is stored in LCS domain at High
Quality. If it does not match, in step 614, the content is
rejected.
[0171] Referring again to FIG. 2, path 228 connects LCS 202 with
satellite unit 210. Referring to FIG. 7, a flowchart depicting the
process for content entering LCS 202 from satellite unit 210 is
provided. In step 702, the content may he watermarked before it is
transmitted to the LCS. In step 704, the content is transmitted to
the LCS.
[0172] In step 706, the content is checked by the LCS. This may
include checking the LCS hash. If the hash matches, in step 708,
the content is stored in the LCS domain as High Quality. If there
is no hash, in step 710, the content is degraded to Low Quality,
and in step 708, the content is stored in the LCS domain. If the
hash does not match, in step 712, the content is rejected.
[0173] Referring again to FIG. 2, path 230 connects LCS 202 with
satellite unit 210. Referring to FIG. 8, a flowchart depicting the
process for exporting data from the LCS 202 to satellite unit 210
is provided. In step 802, the content is retrieved from storage
within the LCS. In step 804, the security of the path between the
LCS and the satellite unit is verified. Once the security is
verified, in step 806, the content is exported to the satellite
unit without a watermark.
[0174] If the security of the path cannot be verified, the export
process mirrors that of an export to a receiver, depicted in FIG.
5.
[0175] Referring again to FIG. 2, path 232 is a path for content,
to be stored in satellite unit 210. In one embodiment, all content
may he allowed to be imported into satellite unit 210, but may he
automatically degraded to Low Quality when it is stored.
[0176] Path 234 is an export path for content rendered by satellite
unit 210. In one embodiment, this content may be marked with a
satellite unit watermark that contains a hash from the satellite
unit Unique ID and any hash that is associated with the content
from an LCS.
[0177] It should be noted that a hash function may be converted
into a digital signature by performing a hash and encrypting the
result of the hash. The uniqueness of the hash can vary with the
hash function, while the digital signature adds a layer of
confidence to the integrity of the data.
[0178] Other types of encryption, including transfer functions, may
also be used.
[0179] Referring to FIG. 9, a flowchart of a method for trusted
transactions according to one embodiment of the present invention
is provided. In step 902, value-added information, or its tangible
equivalent, is provided. This may be provided by a user that wishes
to verify the value-added information.
[0180] In step 904, the perceptible data for verification may be
maintained by a vendor or provider, and may be updated by a
public-key secure digital watermark in the observable packaging (if
applicable). In those cases where security must be high, real time,
or simply faster, key generation or signature generation functions
may be enabled with embodiments of the present invention.
[0181] In step 906, the user provides a public key based on the
identify held in the device to enable an authentication check.
[0182] In step 908, a response may be sent to the user.
[0183] Steps 906 and 908 may be repeated with further prompting for
higher levels of authentication, or for additional checks. If the
remote location provides the confirmation, or if a certification
authority is involved, the response may be sent via secure
transmission lines (e.g., encrypted transmission that can only be
decrypted with the user's device and access to the user's stored
private key). Alternatively, information may not need to be sent in
a secure manner and may be checked upon delivery to the device to
limit any remote communications breaches by unintended third
parties,
[0184] Referring to FIG. 10, a device for trusted transactions
according to one embodiment of the present invention is provided.
Device 1000 may include steganographic cipher 1002. Steganographic
cipher 1002 may be governed by at least the following elements: (1)
a predetermined message; (2) a predetermined key/key pair; and (3)
a predetermined carrier signal (image data, so images will be the
primary data represented and ciphered).
[0185] Transducer 1004 may be provided. Transducer 1004 may include
a charged coupled device (CCD), a personal entropy capture device
(e.g., a retinal scanner, a thumbprint scanner, etc.), a touch pad
(e.g., a pad for receiving a signature), an image capture device, a
bar code reader, a magnetic card reader, etc. Transducer 904
receives the data in a physical format and converts it to an analog
or digital format.
[0186] In one embodiment, the data from transducer 1004 may be
marked with a timestamp for time-critical input.
[0187] Analog/digital converter 1006 may be provided. A/D converter
1004 may be used to convert analog information from transducer 1004
into predetermined digital format. In one embodiment, signatures
may be converted in one format, images that are captured in another
format, and fingerprint/iris scans may be converted in another
format.
[0188] A memory may be provided, The memory may include both
volatile memory, and re-writable memory, such as DataSlim.TM..
[0189] A volatile device may be provided, such as a one time pad
(private key of card holder/user), a one time memory or floating in
the volatile memory to evade capture (stega-cipher computer code).
This may be provided in a tamperproof casing.
[0190] Device 1000 may also include output 1020. Output 1020 may be
any suitable output, including a connection port, a wireless port,
a radio transmitter, etc. Before information is output from device
1000, it may be encrypted. In one embodiment, the information may
be digitally watermarked. In another embodiment, the information
may be digitally signed. In another embodiment, the information is
not encrypted, and instead is transmitted over a secure
transmission channel. Number generator 1008 may be provided. Number
generator may be a random number generator, or it may be a
pseudo-random number generator.
[0191] In addition, the device may include a controller, a power
source, and an input and an output.
[0192] Information may be converted into a humanly perceptible form
(chemical/electrical/magnetic such as a humanly visible chemical
test result, as with a pregnancy tests, an EKC, an MRI or CatScan
image, are all converted into "humanly perceptible form for "human"
analysis) prior to authorization of a transaction/decision
event.
EXAMPLES
[0193] In order to better understand the present invention, several
examples are provided. These example do not limit the present
invention in any way, and are intended to illustrate embodiments of
the present invention.
[0194] 1. Smart Telecommunications
[0195] At present, large volumes of commerce and commerce-related
activities are performed using telephone connections.
Authentication of identity is an ongoing concern in such
transactions. Present technology allows the verification of the
origin of a landline phone call (POT), but offers no assurances as
to the identity of the user. Furthermore, simple identification of
the origin of the call is only useful insofar as that phone number
can be used to index a database of callers. The present invention
allows for bi-directional verification of identity during a phone
call, with the option of partial or full concealment of
identity.
[0196] A consumer may wish to make a purchase on the phone.
Presently, the consumer's identity is established by the seller
using personal information from the consumer, such as a credit card
number, an address, a phone number, etc. However, all of this
information may be known by an imposter. A smart phone transmits
identity information (perhaps embedded as a watermark in the audio
connection), in response to a query from the seller, The receiver
verifies the buyer's identity with a certification authority.
Furthermore, the consumer may also verify the authenticity of the
sellers identity at the same time, by the same method. The consumer
may choose not to respond to certain queries in real time.
[0197] The smart phone may require a level of identity disclosure
before it accepts an incoming call. For instance, telemarketers may
be required to reveal the name of their company before the call is
accepted by the smart phone, Consumers may protect themselves from
fraudulent sellers by requiring such identification. Further,
legitimate sellers may be assured that their customers know that
they are legitimate. The certification authority assures the
consumer and seller that they are receiving authentic
identifications.
[0198] 2. Equity Programs as a Value-Added Component
[0199] Another embodiment of the present invention relates to
methods and means of payment includes a novel means for encouraging
alignment of buyer and seller interests. Similar to cooperatives,
membership programs (in proprietary form, co-branded with a
financial institution, or implemented as a specialty device that
can handle these equity transactions) may be enhanced to offer
buyers the opportunity to purchase options in equity of the
seller's company or related institution. Instead of being given
cash or points, at some fixed point in time, consumers and sellers
may be provided with the opportunity to purchase equity as
available on some public or private market or exchange.
[0200] These options may be built into the functionality of the
actual transaction device and may be coupled with both trusted
transactions or general transaction systems. Settlement of the
option may be based on any known option pricing mechanism (such as
the well-known Black-Scholes model) and predetermination of terms
tor settlement and conversion of the option. This approach
incentivizes and encourages clearer alignment of all market
participants in the value and condition of the equity of the entity
with which transactions are being handled or negotiated.
Independent certification authorities, or infomediaries that are
able to ensure or verify a transaction or related information, may
be used to ensure that such equity programs can be trusted. Any
relevant disclosures concerning legal or financial restrictions are
simply additional value-added components for consideration.
[0201] 3. More Security-Body Movements for Entropy and
Pharmaceutical Use Control
[0202] A related embodiment according to another embodiment of the
present invention includes an interface for detection of body
movements (eye movements, blinks, voice pass phrases, etc.). These
movements may include predetermined sequences of movements that may
be ciphered in a manner similar to encrypting ASCII pass phrases.
This is a novel implementation of human movement in generating
symmetric or asymmetric cryptographic keys. The transducer may
include any number of means of capturing human-based body movements
in real time for instantaneous verification of an authorized user.
Moreover, unlike simple biometrics, a series of body movements
(similar to the act of signing in writing, but likely to be more
difficult to capture for unauthorized misuse--a signature, like a
fingerprint, is able to be observed and copied without permission
or knowledge of the signature author) is difficult to copy.
[0203] The movements or similar biological entropy (transduced from
biomedical, bioengineered, biochemical or biophysical information
that may be made perceptible and encrypted or securely watermarked
for later comparison or real time verification) may be captured by
a transducer of analog signals and converted into digital binary
information used for comparison with any number of stored
corresponding instructions or messages to be decrypted.
[0204] These signals may be multidimensional (2D, 3D, 4D--with a
time component, etc.) to increase the information space and make
discovery of hidden secrets more computationally difficult. Images,
medical or human-condition based, audio signals, video, virtual
reality, multimedia, etc. all provide rich media information in
which to enhance the security of any embodiment contemplated by the
present invention, Combinations of multidimensional media for
varying ciphering options as well as steganographic embedding are
also contemplated as a means for furthering ensuring computational
complexity to any unauthorized user. Steganographic-mapping
(watermarking) or transfer functions (scrambling or "chaffing") may
be combined with encryption ciphers as a means for making each
unique implementation or tangible device--serialization or
personalization of a. method for engaging in trusted transactions,
high risk, information-intensive or sensitive decision (military
use, security use, restricted government use, privacy use, or any
number similar commercial or noncommercial decision or transaction
events).
[0205] Additional embodiments include actual control over the use
or access to pharmaceuticals based on medical risk, condition or
personalized advice to the user, Tangible methods for transfer of
chemical, biological or physical agents intended for medical use or
individualized control based on third party conditions (legal,
medical, governmental, etc.) are governed by manipulation of the
apparatus, device or system used to introduce foreign agents
(informational, intangible or tangible) into patients (the
intended, authorized or verified user).
[0206] Highly secure and artificial environments, such as aircraft
flying simulations or visual financial trading information, may be
representative of more risk to owners of actual tangible planes or
tangible assets related to any financial information. Recognition
of a digitized iris does not enable movement based confirmation of
future secrets (the movements) that may be changed, destroyed or
updated to ensure consistent or higher degrees of security
maintenance. For some body movements, it may be possible to
maintain better security than with written information. In other
words, certain body movements may be prevented, or made difficult
to perform even under rigorous demand by unauthorized agents.
Blinking or other facial movements may be made impossible to verify
the real time identity of the user. This adds a layer of security
and increases the difficulty of defeating a cipher or a series of
related ciphers (encryption-based or steganographically-based,
where the digitized signal has humanly-perceptible fidelity or
characteristics) depending on access or sensitivity of information.
It also maybe psychologically or human-rule driven. Certain humanly
observable body movements, or detectable "telemetry-type" data
(brain activity, heart beat, pulse, or any other medically
observable information) may be either unique to an individual or
simply general to certain behavior. This data may be important to
use as a means of preventing poor decision-making, or requiring
higher diligence before transacting or executing a given operation.
At the least, the movements are a means for predetermining and
assisting the generation of a binary key or seeding the generation
of a cryptographic key, message or signature.
[0207] Any particular instance may be successively stored in
subsets of any primary value information or value-added components
(single key or key pair associated with a single message or
signature to further serialize data that may have steganographic
capacity for imperceptible embedding in the carrier signal, primary
or value-added components data). The operation may be highly
demanding, or may require human-based or driven or initiated
decisions. The instructor, or the user, may have predetermined the
conditions that indicate confidence or lack thereof at the time of
the verification or authentication of the user. This may be for
security reasons, or simply risk management, as information is
increasingly processed at higher speeds and may require greater
care in ensuring information data integrity. As well,
humanly-observable (and convertible into binary data for
deciphering) movements enable a form of bridging analog, human
trust with digital or mathematically provable, actuarially,
statistically, deterministically known or predictable measures of
risk and trust. This novel feature is an additional benefit over
the prior art and ensures future human-like characteristics in
"digital" (underlying, "measurable" or "estimable" data integrity,
authentication and confidence), electronic (analog transducers and
transmitters), or binary transaction systems. Further security or
serialization of transaction event information (human movement or
observable condition used for secret key or equivalent generation)
enable additional forms of trusted transactions.
[0208] Additional security may be assured with temporal-based
limits on human body movement or biologically observable human
condition (by use of a medical or human directed transducer).
Interlocking keys and messages with blind signatures, or onion
routing transmission techniques to obscure the identity of the
user, are further enhancements that may guarantee a high level of
privacy to the user of the system or device. Information formats
may be encrypted or have stored. primary or value-added component
information that has to arrive to the user without any digitally
evident tampering for the user to make the best possible decision
regarding the observed information.
[0209] Unlike the prior art, embodiments of the present invention
consider the perceptibility of information to bridge human trust
and confidence with cryptographic or "mathematical" measures or
estimates of "security," "data integrity" or "trust." This is novel
to the art of data security and secured transaction or transmission
technologies.
[0210] 4. Algorithmic Information Theory (AIT) for Additional
Security
[0211] By implementing predetermined indications of mathematically
provable randomness, the ability to discover secrets and human
choice, based on unprovability or incompleteness, as discussed and
is well-known in the art as originating with (yodel (incompleteness
theorem) and Turing (halting problem, uncomputability). Chaitin
"discovered" randomness, stating essentially that randomness can be
described mathematically, and thus differentiations between
discrete and infinite randomness are logically observable. Because
truth is relative in a quantum mechanical sense, degrees of
credibility concern the level of trust that may be offered in any
trusted transaction system. While the primary value that concerns
us is information, the ability to describe programming size
complexity (that is optimized functional data) enables
self-limiting software to be programmed. To the extent that trusted
transactions can never be physically perfect operations, uniqueness
of information, as both data and code, is particularly important to
providing higher security when computational cost and bandwidth is
extraordinarily cheap,
[0212] Essentially, choice over answers to questions that cannot be
characterized as "True" or "False," such as "This statement is
false," have inherent randomness and. are thus ripe for paradoxical
response. More intricate paradoxes, Berry's Paradox, Turing's
halting problem, as well as Chaitin's definition of "randomness,"
are sure to enable predictable infinite and finite (discrete)
randomness with which to seed and cryptographic secret or
generation of a symmetric, asymmetric key or digital signature.
Human perception as a means for enabling analog trust may be made
inherently more secure by choosing responses to paradoxes that have
no computable value. That Chaitin can describe "randomness" with
logically structured instructions for the halting problem, in LISP
or C programming languages, including the computer programming
language of Mathematica, enabled the development of a randomness
constant.
[0213] The equations of randomness may be implemented in software
and offer a unique and novel means for further securing the
generation of cryptographic or steganographic seeds, secrets, keys
or messages. Of course, differences between any of these
information elements as to the means for securing or authenticating
data would enable flexible architectures combining various ciphers
and methods for arriving at a rule for validation, authenticity,
data integrity, confidence or enabling any subsequent manipulation
of the associated data (primary value-added or value-added
components).
[0214] 5. Entertainment Media Exchange
[0215] According to one embodiment of the present invention, the
device may be used for the exchange of entertainment media, This
may include audio, video, multimedia, etc, in such an exchange, the
perceived risk of value-added information piracy is relatively high
for the seller or provider, while the perceived risk is relatively
low for the purchaser. The obvious risk is that all potential
"consumers" of the media access and copy the entertainment media
for free. For music or video, or similar entertainment good,
according the present invention provides the following structure
may be used.
[0216] a) Fragile Watermark Structure
[0217] The fragile watermark, according to one embodiment of the
present invention, can actually hold an entire value-added
component, encoded in the least significant bit (LSB) of each
16-bit sample. This gives a data rate of 88200 bits per second in a
stereo CD file, or a capacity of 1.89 M in a 3 minute song. This is
an immense capacity relative to the expected size of the
value-added component (100-200K).
[0218] The fragile watermark is preferably bound to a specific copy
(Unique ID) of a specific song (Unique ID), so that it cannot be
transferred to other songs. This binding can be achieved through
use of a hash in the following sequence:
[0219] (1) A block of value-added component is encoded into a block
of samples.
[0220] (2) A hash of the value-added component block and a random
number seeded by the owner's identity (Device or system Unique ID)
is generated and encoded into the subsequent block of samples.
[0221] (3) A hash of the first two blocks of samples and a random
number seeded by the owner's identity is generated and encoded into
a third block of samples.
[0222] (4) Repeat steps 1-3 as necessary.
[0223] Each value-added component block may have the following
structure:
TABLE-US-00001 ] { long BlockIdentifier; //A code for the type of
block long BlockLength; //The length of the block . . . . //Block
data of a length matching BlockLength char IdentityHash[hashSize];
char InsertionHash[hashSize];
[0224] An application can read the block identifier and determine
if it recognizes the block type. If it does not recognize the block
type, it can use the BlockLength to skip this block.
[0225] Certain Block Types are required to be present if the
value-added component is to be accepted. These may include and
identity block and a value-added component Hash block. The Block
Data may or may not be encrypted, depending on whether the data is
transfer-restricted (value-adding) or simply informative. For
instance, user-added value-added component data would not need to
be encrypted. The BlockIdentifier would indicate whether the block
data was encrypted or not.
[0226] b) Robust Open Watermark
[0227] This is the mark that may indicate non-legacy content. In
one embodiment, there may be two possible settings. "1" indicates
non-legacy content that must be accompanied by a authenticable
value-added component for entry into the domain (e.g., EMD or
Electronic Media Distribution media content). "0", on the other
hand, indicates non-legacy media that was distributed in a
pre-packaged form (e.g., CDs, DVDs, game software, etc.). "0"
content may or may not have a value-added component. "0" content
may only be admitted from a read-only medium in its original file
format a "0" CD may only be admitted if it is present on a Red Book
CD Specification medium).
[0228] c) Robust Forensic Watermark
[0229] This watermark may not be accessible to the consumer in any
way. It may be secured by a symmetric key held only by the seller
(or an asymmetric key pair that may be desired for some
embodiments). A transaction ID may be embedded at the time of
purchase with a hash matching the symmetric key (or key pair). The
watermark may then be embedded using a very low density insertion
mask (<10%), making it very difficult to find without the
symmetric key. Retrieval of this watermark is not limited by
real-time/low cost constraints. The recovery will only be attempted
on pirated material. A recovery time of 2 hours on a 400 MHz PC is
reasonable.
[0230] 6. Additional Parameters for Value-Adding Components
[0231] Physical shipment of packaged goods or services (value-added
information) is anticipated as being a potential option to
consumers or purchasers as well as sellers and providers. That the
value-adding information may be packaged or represented tangibly
does not obviate the need for trusted transactions to ensure
payment and the appropriate division of rights and responsibilities
for various goods (a DVD for music or video), services (smart
credit card or insurance card) or markets (trusted telephone
system, government identification schemes). This type of
transaction represents additional benefits over embodiments in the
existing art--on-demand trusted transactions and physical
manufacture/delivery of goods is enabled, without risk to the
overall system and its value-added information security. This
amounts essentially to serializing or personalizing, depending on
the perspective in the transaction, each and every transaction,
while building trusted transactions for the benefit of the
marketplace for goods services and information.
[0232] 7. Financial or Insurance Device
[0233] The present invention enables systems and supported devices
that are useful in situations Where parties need to have
pre-defined limits to risk exposure, such as an insurance policy or
a claim. These systems are generally characterized by an emphasis
on transmission and data security, which reduces the perceived risk
of the insurer (a seller of risk coverage for predetermined
events). To the extent that insurance takes into account the
history and existing condition of an asset, a measure of context or
structure (tangible as well as intangible) to he covered, as well
as an economically-based replacement value (though to confuse
matters, there are also issues concerning such items as after
market versus brand new, brand versus generic, etc.), there exist
differences with more transparent financial devices. Financial
devices (essentially a "credit agreement" or credit facility based
on an imprecise estimate of condition but also experience or trust)
rely on the ability, perceived or actuarially observable, to repay
credit extended on behalf of the device holder. Whereas financial
or credit history is transparent in many cases, private information
about an individual's history or condition are perceived to be have
higher implicit value to the user. Financial devices and insurance
devices converge at those points where privacy or personal
information are equivalent with financial or credit information.
Both types of risk have differing requirements for updating or
adjustment over the course of use of a particular line of credit or
insurance policy.
[0234] Cars may be embedded with telemetry sensors to determine the
real time condition of various components, such as the frame,
engine, brakes, or any combination of components mutually deemed to
justify such monitoring. Alternatively, a smart card-like device
equipped with a transducer may be used to "capture" images of items
that are packed (for travel insurance purposes), insurable items in
a residence (for homeowner's insurance purposes), etc. Any image
captured may be securely watermarked by the device and then
exported to an insurance provider via a transmission line (an ATM,
a wireless connection such as a mobile phone, a PC modem
connection, etc.). An insurance provider may offer such services at
auto service/repair facilities, airports, etc. with a mutual
reduction in claims costs and adjustments costs.
[0235] Medical information may similarly be digitally stored,
securely watermarked, and time-stamped (for any perceptible data
stored, such as images or voice) for reference to an individual's
health. based on varying levels of access to stored information,
which may be distributed among different physicians or handled by a
central medical information infomediary. The secured image may be
sent to an insurance provider as a secured image (both the device
and storage facility may independently verify the security or
tamperproofing of the perceptibly represented information). The
doctor, patient, health care provider, government agencies can all
have varying degrees of access that can be made transparent to the
patient. This is an inherent benefit over the prior art in that the
patient can see those records that are then watermarked and
securely stored.
[0236] Additionally, the present invention provides the novel
feature of enabling the same information, at the request or demand
of the patient, to be sent to a personal or secure storage "space,"
so that patients may have more accessibility and control over their
own medical records and medical conditions. In one embodiment, the
information may be provided as digitized bits. In another
embodiment, the data may be provided in a tangible form.
[0237] The information may be stored as tangible records or
intangible, bit-represented records. Doctors may use tamperproofed
signals (watermarked audio, image, video, virtual reality, any
humanly-perceptible signal) and records that are perceptible to
lower insurance costs and potential liability. The prior art
ignores the mutual benefits afforded by bidirectional information
exchange (that can be tamperproofed with secure watermarking) and
transparency in creating opportunities for trusted
transactions.
[0238] Additional data, such as the transaction information that
may be evidenced on a credit card bill or statement, may also be
automatically associated with the stored image(s) for later use. In
one embodiment, the user may send the same secured data to a
private data storage facility, or create personalized records,
which may serve as a secondary set of records against which other
data sent to the insurance or financial provider may be verified or
validated. According to another embodiment of the present
invention, authorized mechanics, physicians, and pharmacists, may
add to, but not access or manipulate, previously stored data. These
individuals may also be bound by rules for establishing the history
and condition of any person or physical good that is being
underwritten or financed.
[0239] The present invention provides certification authorities the
ability to determine the authenticity of data. In cases where
public-key steganography or cryptosystems are preferred, the
embodiments extend to those implementations as well. Moreover, they
enable secure transmission capabilities over unsecured data
transmission lines.
